Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming an indicia on a record disc display by a hot stamp printing method and an apparatus directly used for carrying out this method.

Conventionally, the display on the display section of general record discs, such as the title of the song, lyricist name, composer name, performer name, product number, manufacturer name, etc., related to the recorded content, such as letters, figures, or symbols, etc. This is done by pasting a printed paper label onto the record.

However, attaching this label to the record during the press molding of the record increases the molding process, which has disadvantages such as an increase in defects caused by the label and an increase in the press cycle due to the attachment of the label. There is. Furthermore, when such paper labels are press-molded together with record materials, the following disadvantages occur. In other words, during press molding, the paper label was misaligned (v), the adhesion was insufficient (D), and trying to make a new record by playing a defective record. In some cases, the paper fibers become deeply embedded within the recording material. Therefore, when a recorded record is played, a lot of noise will be generated. In order to solve this drawback, a technique has recently been proposed in which characters or symbols to be displayed are molded at the same time as the record is molded. This technology uses press processing or injection molding to form uneven areas on the display area of a record (also called the label area), and uses these uneven areas to create a display. If a mother master disc having a pattern is prepared, the display part can be easily formed by successive transfer by pressing or injection molding. However, with this technology, it is impossible to display multiple colors as in conventional paper labels that are pasted to display. Therefore, very recently, it has been proposed to apply color to the convex portions by pressing a colored film onto the display portion having the concavo-convex portions. According to this proposed method, it is possible to display characters, symbols, figures themselves forming a display, or their peripheral parts in multiple colors. However, since this method involves pressing a colored film having one color or a color-divided pattern onto the display section, it is impossible to display characters or symbols in a desired area in a desired color. The present invention has been made in view of the current state of affairs, and provides a method for easily displaying a display without forming an uneven part on the display section of a record, and a method for implementing this force method. It provides a device for direct use.

The present invention will be explained below with reference to the drawings.

First, with reference to FIG. 1, a record forming apparatus including a device for forming a display part of a record, in which the method according to the present invention is carried out, will be described. Reference numeral 1 denotes a record record molding machine that molds records by injection molding or press processing, and is a device in which the sound groove pattern of the record and the shape of the record are formed.

Colored films 6 are arranged on both sides of the record disc 5 so as to cover the corresponding parts of the label. This colored film is arranged so that the side to which the coloring material is adhered is in contact with the corresponding area of the label, and then wound around two reels 7 and 8 installed above and below. The running of the colored film 6 is carried out by being fed out from a reel 7 and wound onto a reel 8. Further, a similar colored film 23 is arranged next to this colored film. This colored film 23 is also wound around two reels 24 and 25 installed above and below, and its running is performed by being unwound from the reel 24 and wound onto the reel 25. However, the color of the coloring material of this colored film 23 must be different from that of the colored film 6. These two colored films 6, 23 are moved together in the direction indicated by the arrow in the figure. The amount of movement must be equal to the length between the center of the width of the colored film 6 and the center of the width of the colored film 23. When the amount of movement is determined in this manner, when the colored film 23 is moved in the X direction from the position shown in FIG. 1, the colored film 23 is brought to the original position of the colored film 6. When the colored film 23 comes to this position, the side of the colored film to which the coloring material is attached will face the label corresponding portion of the record disc 5. In addition, a pedestal 14 is installed above the record 5 in a portion facing only the colored film 23, and this pedestal 14

, 20'' so that it is fed in the direction shown by arrow A in the figure.On the outside of this colored film, there are hot stamp presses 11, 11' facing the label corresponding parts 5a, 5a'. This press machine 11 has a pressure bonding plate 11a, a heater 11b, and a piston 1.
1c and an air cylinder 11d. Note that the other presses 1 have the same structure as the press 11. By the operation of these presses, the side of the colored film to which the colorant is attached is pressed onto the label corresponding portion 5a and 5b. The label portions 5a and 5b are colored by being pressed and heated.The front surface of the pressure bonding plate 11a of this press is made flat.Therefore, as shown in FIG. When the press 11 is energized as described above, all the coloring material in the area pressed by the pressure bonding plate 11a is transferred from the colored film to the label corresponding parts 5a and 5b of the record disc 5. A pedestal 14 is installed between two colored films on the soil flow side of the film 23 (the upper blade in the device shown in FIG. 4). It has two planes 14a, 14b having the same or slightly larger area.On these planes 14a, 14b there is an axis 16 or axis 17 (shown in FIGS. 1 and 4). ) are rolled out from a lying position, and are guided by guide rollers 21, 21'. , 14b are installed with press machines 22, 22' for hot stamping.
2' has the same structure as the press machine 11 described previously. In Fig. 4, these press machines are shown in a lying position when they are not in operation, and in Fig. 5,
These presses are shown in a state in which they are operated. The press plates 22a and 22a' of the press machines 22 and 22' for hot stamping are composed of plates having convex portions forming characters, figures, symbols, etc. to be displayed on the display section of the record. Next, the method according to the present invention will be explained using FIG. This figure 6 is similar to figures 2 and 3.
Figures 4 and 4 are simplified illustrations of the main parts of the display section forming device 4 shown in FIG. 5. The same parts as in the previous figure are given the same reference numerals. First, as described above, as shown in FIG. 6A, the colored film 6 is placed so as to cover the label corresponding parts 5a and 5b of the record disc 5, and the side 6b to which the coloring material is attached is attached to the label corresponding part. After arranging the labels so as to face each other, the hot stamping press 11 is energized as shown in FIG.
A colored film 6 is pressed onto a.

Although FIG. 6 only shows the label corresponding part 5a on one side of the record disc 5, these operations and the movements to be explained from now on are shown in the label corresponding part 5b on the back side of the record disc 5. Seki 1 will also be held. In this case, the other presses 22 have not yet been put into operation. Next, when the pressure of this press machine 11 is released,
The piston 11c moves back (displaces upward in FIG. 6) as shown in FIG. 6C. When the pressure bonding plate 11a separates from the colored film 6 in this way, the colored film 6 is automatically peeled off from the label corresponding area 5a due to its tension, and the coloring material is transferred to the entire surface of the label corresponding area 5a. Next, the aforementioned capstan roller 20 is rotated to run the colored film 6 in the direction shown by the arrow A in the figure, and the portion 6c from which the coloring material has fallen is brought to a position where it does not face the label corresponding portion 5a. On the other hand, the adjacent colored film 23 is placed so as to cover the flat surface 14a of the pedestal 14 as shown in FIG. As shown in E, the sheet 15 placed on the pedestal is pressed by the hot stamp press 22.

As shown in FIG.
5. Coloring material corresponding to the above-mentioned characters, figures, symbols, etc. is transferred to the soil. When this transfer is performed, portions of the colored film 23 that do not have the coloring material corresponding to the above-mentioned characters, figures, symbols, etc. are formed. Although not shown in FIG. 6, the sheet 15 after the transfer is made to run by a suitable means so that the new portion faces the colored film 23. The operations described above are performed in the state shown in FIG.

Next, the colored film 6 and 23 are moved in the direction indicated by X in FIG. 1, and the colored film 23 is brought to the position before the colored film 6 was moved. During or after this movement, the colored film 23 is made to run in the direction shown by the arrow A in FIG. (Figure 6G). Thereafter, the press 11 is energized to perform crimping (FIG. 6H). When the pressing press 11 is released after this crimping process is completed, the coloring material in the area crimped by the crimping plate 11a is transferred to the label area 5a, as shown in FIG. 6.
Transferred onto the coloring material above. Therefore, characters, figures, symbols, etc., are displayed in the color of the coloring material of the coloring film 6, with the color of the coloring material of the coloring film 23 set in the background on the corresponding part of the label of the record disc 5. When the display is made in this way, the holding of the record holder 26 is released and the record 5 is sent to the next process, that is, the record straightening device. Record board 5 is sent. In addition, along with this new record delivery, or the record record holder 26
Detecting that the holding function of the coloring film 6 is released, the colored film 6 23 is moved in the opposite direction to the direction indicated by the arrow x in FIG. 1, and is brought to the position shown in FIG. arranged,
The movement described above will take place again. Although the method according to the present invention has been described above based on one embodiment of the apparatus, it can be carried out using various types of apparatuses as long as it does not go against the gist of the present invention. As explained above, in the present invention, the label section (also referred to as the display section) of the record has a second
Immediately before pressing the colored film on the label, the coloring material in the area corresponding to the characters, figures, or symbols to be displayed was removed, so that the corresponding area of the label was colored with the first colored film. Since the second colored film is crimped afterwards, the display can be displayed in multiple colors without providing any unevenness on the display section of the record.
Further, since it is not necessary to form an uneven portion on the display portion, there is an advantage that the molding of the record disc can be carried out easily and successfully as in the conventional method.
